Cant Boot from CD using USB Keyboard

This has happened to me several times, but it always catches me off-guard.

I was trying to repair a windows installation and needed to boot from the WinXP CD. I am using a USB keyboard, which was not a problem at all at first, as I was able to press F9 and enter the BIOS. From there I set the computer to boot from the CD. When the computer restarted and asked me to:

Press any key to boot from the CD-ROM…

I was unable to do so. I never found a fix and it was necessary for me to install a PS/2 keyboard to get the computer to boot from the CD. I later realized that running “sfc /scannow” from a command prompt (available by typing “cmd” in the “Run…” box on the Start Menu) combined with a registry backup would have cleared up my problem, but hey…

Some modern BIOS revisions have an option to enable USB keyboard support from the BIOS or OS. Setting this to BIOS will clear up this problem in most cases (mine didnt include this option, but a quick test on a computer at work.

It is good practice to have a PS/2 keyboard and mouse always at hand, just in case something goes wrong with your wireless devices.
